TO ALL WII-OM' IT MAY CONCERN: Y

Be it known-that I, JOSEPH H. SPRINGER, of the city and county ofPhiladelphia, and State of Pennsyl- Vania, have invented a new andimproved Governor; and do hereby declare that the following is a fuli,clear,

,and exact description thereof, reference being had to the accompanyingdrawings, making a part ofthe specification, in which- Figure lis aperspective view of the improved governor. Figure 2 is a front elevationand section through the forcing-pump. 4Figure 3 isa transversesectiontalicn in the vertical plane indicated by red line me; in 2.Figure 4 is a longitudiriiilso'ction looking towards the pump. Similarletters of reference indicate corresponding parts in the severalfigures. This invention relates to a newand improved governor, whichisadapted for use upon marine engines, as

`well as portable and stationary lands-engines, and which is soconstructed that, while greater regularity, delicacy, and steadiness ofaction are secured than are attainable by the old 'forms ofgovernors,any desired range or amount of movement necessary for regulatingpurposes can bc obtained.

The nature of my invention consists in a receiver, which is providedwith a movable cover or elastic diaphragm, and also with an outlet,having an adjustable valve applied to it, for'regulating the escape ofiuid that is forced i'nto the receiver by a supply-pump, said partsbeing constructed, adjusted, and connected with the throttle-valve, andalso with the slide-valve rod, or some other proper part of an engine,as will be hereinafter explained, so that, should the speed of theengine exceed or fallshort of the prescribed limit, the'lluidwill beforced into the rceeiverfaster in the one case', and slower in theother, than it escapes; by which means the cover of tlicreceiver iscaused to 'operate upon the throttle-valve, and open or close thisvalvcmore or less, according to the regulation required.

To enable others skilled in the art to understand my invention, I willdescribe its construction and operation.

` In the `accompanying drawings, A represents a receiver for water, air,or other fluid, which'receiver may be made of any suitable shape and ofany required capacity. A

The t'op, B, of this receiver is composed ef India rubber, or othersuitable flexible material, impervious to air or water, which isconfined tightly in place by means of a clamp-ring, a, held down inplace by screws and nuts.

To the centre of this flexible top or diaphragm Bis suitably secured alink, b, which is'connected to a lever, C. This lever is pivoted to afixed standard, b', upon the top of the receiver, 'and its opposite endis to be connected in any suitable manner to the rod of a4tlnottle-valve, which regulates the admission of steam to thevalve-chest of the engine.

To the centre ofthe bottom ofthe receiver A, a pipe, D, is applied,which communicates with branch-pipes E E, leading .into apump-cylinder,v F, near its extremities, and also leading down into achest', G, for containing the iluid to beforced into the receiver. Thepipe D also communicates with a central pipe, II, which also leads intosaid chest G, as shown in the drawings.

The pump-cylinder F may be secured fast to the top of chest G, as shown,and in this cylinder Works a solid piston, J, the rod J of which shouldbe connected in a suitable manner with the rod of the slide-valve of thesteam-engine, or with any other convenient part of the engine which willcommunicate to said piston a.

steady movement.

In the two branch-pipes E E, suitable valves, L and j, are applied, forthe purpose of allowing iluid to'be drawn from chest G and forced intothe receiver A. The valves hopen upward, and allow the uid to be raisedabove them by the action of the pump-piston; they then close, and allowthe fluid to be forced upward intothe receiver Af The valves j preventthc'uid which is forced above them from being drawn back by thepump-piston.

The centralpipe D communicates'withftbe pipe H by means'` of a. valve,K, which has a. hand-wheel, L, applied o n its stem, by'means of whichthe.valveopening can be increased or diminished in size, ascircumstaneesmay require. l y y Y v When a reciprocating motion is given,to the piston-rod J by the starting of the engines, andthe opening ofvalve K, properly adjusted, 'fluid will be drawn from chest G and'forced into the receiver A, from which latter it will escape, throughpipes Dand H, ba ck.again into the s aid chest. 'As long as the enginereceives a regular motion, there will be no more Huid forcedinto thereceiver A thanl 'can escape through said pipes Dl H into the chest G.Should thespeed of the engine be diminished, the fluid willescape fasterfrom the` receiver than it enters it, which will allow the diaphragm Bto descend, and thus open the throttle-valve more or less; and, on theother hand, should the speed of the engine be increased, the Huid willbe forced into thc receiver faster than it canl escape therefrom, andconsequently it will cause'the diaphragm Brto rise or expand, andthereby v close the throttle-valve more or less.

kBy means of the valve K the opening through which the Huid is allowedto escape from the receiver A can be nicely'regula'ted, so that the uidshall only escape at' a given rate. v

Having described one practical mode of carrying my'invention'intoeffect, I- wish itto be understoodtthat Ido not conne myself totheprecise 'instrumentalities herein set forth, as these may be modified inmany particulars without changing the principleof myinvcn'tion.- Ihaverepresented a double-acting forcing-pump,

which is adaptedfor forcing water orfoil yinto the receiver, .butI donot coniine'myself 'to such a force-pump, as`

one which is adapted fcr supplying atmospheric air might be employed, ifit Vshould be foundpreferable to use air instead ofwater. or oil. Y

I have also -represented 'and described a receiver which is providedwith 'a fiexiblc diaphragm, which diaphragm is caused tojexpand moreorless, according to the 'amount of pressure beneath it, and in this wayoperate, through thc-rnedium of suitabley connections, upon'athrottle-valve.

` Instead of this diaphragm a movable'piston, o'r tightly-tting slidingplate, might bc employed. I prefer the use' ofthe diaphragm because itis fr ictionless in its action, which wouldnotbe-the case with a pistonor slidingplate I am 'awa-re of the references cited in odcial lettersdated May 9th and May 25th, 1868,'a'nd therefore I do notclaimanythingshown in said contrivances; but having described one'`practical modeof carrying out my invention,v f v What I claim as new,and desire to secure by Letters Patent, is-

ill. The arrangement of the regulating discharge-valve K, intermediatebetween the reservoirG and the receiver A, and in the relation'specied-toithc supply-pipes E of the force-pump F, whereby the: fluid or air'which Hows into the receiver is made to escape therefrom faster erslower than the supply, as'the case may require, and pass back into thereservoir, to be used repeatedly, all substantially in themanner hereindescribed.

set forth.

2. llhenrrangement of the receiver Awith reference to the connections ofthethrottle-valve of the engine,

central holloweolumn D H, intermediate valve K, pipe's E E, valves j j,and 'fo'rce-pumpF, substantially as JOSEPH H.v SPRINGER.
